2.2 Principle of operation
The horn protection is suitable for Micropilot FMR51/FMR57 level measurement devices in
applications with strong buildup and condensation inside the horn antenna. Thanks to seals
on the horn protection and antenna socket, moisture penetration can be prevented. The
contact ring provides an electrical connection between holding ring and horn antenna.
When using the horn protection, it is not possible to apply purge air through the air purge
connection of the FMR57 as the antenna is sealed by the protection.
